Resumen
GALICIA, Arturo García et al. Platelet / spleen ratio for the diagnosis of esophageal varices and the risk of bleeding in patients with liver failure. Rev. Fac. Med. Hum. [online]. 2021, vol.21, n.2, pp.269-274. ISSN 1814-5469. http://dx.doi.org/10.25176/rfmh.v21i2.3708.
Introduction:
Upper gastrointestinal bleeding of variceal origin has a high mortality. The platelet count/spleen major diameter ratio may be a useful noninvasive parameter to predict esophageal variceal bleeding in cirrhotic patients
Objective:
To determine the sensitivity and specificity of the platelet count/spleen diameter ratio for the diagnosis of esophageal varices with risk of bleeding in patients with hepatic insufficiency.
Material and Methods:
Process study, performed in a Second Level Medical Facility, in patients with liver failure who underwent ultrasound, blood cytometry, liver function tests and endoscopy. Sensitivity and specificity of the platelet/spleen ratio were assessed in patients with esophageal variceal and bleeding risk.
Results:
There were 70 patients: 28 women, 42 men; main cause of liver failure in men was ethylism in 31 patients and hepatitis C virus in 20 women. The spleen-platelet ratio has a sensitivity of 90%, specificity 83%, false positives 16%, false negatives 9%, positive predictive value 94%, negative predictive value 75%, prevalence of 74% and diagnostic accuracy of 88% to diagnose esophageal varices with risk of bleeding.
Conclusion:
Platelet/spleen ratio is a useful, non-invasive study to diagnose esophageal varices with bleeding risk, in hospitals where endoscopy is not available.
